That felt so good that Gina repeated the process, then pulled down Claire's dress, tugged off her bra, and smeared her boobs with chocolate. Soon Olivia's mouth was sucking Claire's clit as Gina licked her tits clean.
That did it for Claire -- she orgasmed so hard she almost started crying. Very pleased with Olivia's performance, Gina fed her some cake and then they adjourned to the bedroom.
"I almost forgot," Gina said to Olivia. "I still owe you a spanking." Once she had tied Olivia's hands behind her back and bent her over the bed, she turned to Claire. "Want to help?"
"But of course," said Claire. "Bad girls like this need to be spanked severely."
They took turns smacking Olivia's ass and when she had been punished enough, Claire bent down to finger and lick her pussy. It was incredibly creamy and flavorful -- maybe the best thing she had tasted all night, and that was saying something. Meanwhile Gina got out her strap-on and took up a position right behind Claire, who was so preoccupied that she didn't know what was happening until she felt the tip slide into her. She let out a high-pitched moan of surprise more than pleasure, then another, lower one as the full length of the dildo filled her. Claire looked back over her shoulder at Gina, who winked, and then turned and resumed working on Olivia, who had taken the opportunity to roll over on her back and spread her legs.
When Gina decided that Claire had been adequately fucked, she stood up and took off the strap-on, handing it to Claire. Then she climbed up onto the bed and sat with her back against the headboard, looking down expectantly at Olivia, who rolled onto her side so she could kiss and lick Gina's downy-soft thighs. She didn't stop there, of course, and soon she was stabbing her tongue between Gina's pussy lips as Claire penetrated her from behind.
Finally, much later, they were all fully satisfied and lay quietly entwined on the bed. Olivia felt incredibly contented laying there with Gina on one side and Claire on the other, but then she glanced at the clock and realized it was past her curfew. She wished like hell that her mother wasn't so stern about enforcing the rules, but it was a school night, and she had no choice but to wriggle out from in between Gina and Claire and get dressed.
Even worse, Claire made no move to follow her. Olivia really didn't like leaving the two of them alone together, but what could she do, tell Claire she had to go? That would be incredibly rude, and it wasn't her house anyway. She was left with no alternative but to kiss them each and say goodnight, stopping on her way out to look back and see Claire rest her head on Gina's shoulder. Sighing, Olivia reluctantly turned and headed home.
